CORK AND'IVIETHOD OF PREPARING SAME.A

SPECIFICATION forming part of Letters Patent No. 686,008, dated November 5, 1901.

Application filed J'une 24, 1901i Serial Non 65i843. (No specimens.)

Be it known that I, GEORGES AUGUSTE TRoMBERT,a citizen of the Republic of France, residing atLyons, France, have invented certain new and useful Improvements in Corks and Methods of Preparing the Same, of which the following is a specification.

The object of the invention is to obviate the unpleasant cork taste which interferes so injuriously with the iiavor of mineral waters, wines, and other bottled goods and to prevent the introduction of cork-dust or of drops of dirty water, which often ooze out from wet corks under the compression induced by the act of corking.

The invention consists in providing the cork with two coats of the nature and applied in the manner hereinafter described.

ln the drawings, Figure l is a central longitudinal section through a cork with the primary coat applied thereto, and Fig. 2 is a like section showing the second and final coat applied over the .first A is a cork cut to shape from the bark and coated by immersion or otherwise with one or more layers B of collodion which has been suitably combined with vaseline or vaselineoil to render it elastic, thereby avoiding the unpleasant taste communicated when castoroil is used for the latter purpose. A preparation of cellulose dissolved in alcohol and ether is then exposed to the air at a suitable prevented from coming in contact with the liquid and spoiling its flavor.

l. The method herein described of preparing corks for use, consisting in iirst coating them with an elastic layer of collodion mixed with vaseline then applyingto said layer a coat of cellulose dissolved in alcohol and ether and allowing the spirits to evaporate, thereby depositing a permanent layer of cellulose over the elastic layer of collodion.

2. A cork having upon its surface an elastic layer of collodion and vaseline and over this a layer of cellulose.

In testimony that I claim the foregoing I have hereunto set my hand this 10th day of J une, 1901.
